Getting Started

Clone repository

To clone respositary, please see our community of practice page.

Set up environment

There are two options to set up the python enviroment:

  1. Pip using requirements.txt.
  2. Conda using environment.yml.

Users would need to delete as appropriate which set they do not need. For details, please see our virtual environments in the community of practice page.

To set up the NCMP_INYEAR package enter the commands below (run one line at a time) in Anaconda Prompt (terminal on Mac/Linux):

pip install --user -r requirements.txt

or if using conda environments:

conda env create -f environment.yml

National Child Measurement Programme (NCMP) background

The National Child Measurement Programme (NCMP) is a key element of the Government’s approach to tackling child obesity by annually measuring the height and weight of children in Reception (aged 4–5 years) and Year 6 (aged 10–11 years) in mainstream state-maintained schools in England.

Local Authorities (LAs) in England measure children during the school year with the programme running between September and August each year to coincide with the academic year.

The data used in this project is provisional and based on extracts from the NCMP system at a particular point in time within the submission period.

This project produces the required data tables for the provisional publication.

Running the publication process

There are two main files that users running the process will need to interact with:

Before processing a new set of extracts, the parameters_inyear.py file will need to be reviewed and values updated as required.

This file specifies the input and output filepaths, the year filters, LA exclusions/updates, etc., and also allows the user to control which table outputs are generated when the process is run.

The publication process is run using create_publication_inyear.py. This script imports and runs all the required functions for the table outputs specified in the parameters file.
